Supreme Court Rejection of WARF hESC Patent Challenge Discussion

The challenge to the WARF/Jamie Thomson patents/IP on human embryonic stem cells (hESC) is at an end.

The US Supreme Court declined to hear the case.

Earlier, the USPTO had turned down the challenge leading to a winding road in the courts.

What do you all think of this stem cell IP challenge and the outcome?

The hESC IP includes 3 patents: 5,843,7806,200,806, and 7,029,913.

For two great stories with helpful background on this development see here and here by David Jensen and Bradley Fikes, respectively.

Scripps stem cell researcher Jeanne Loring was a driving force in the challenge.

You can read a newer piece that Loring did on the Hwang hESC patent situation here.
